Arm has made the strategic decision to deprecate the TC1 platform. Consequently, software development and the creation of fast models for the TC1 platform have been officially discontinued. The TC1 platform, now considered obsolete, has been succeeded by the TC2 platform. It's noteworthy that the TC2 platform is already integrated and supported in both TF-A and CI repositories.

TC Total Compute Platform
|
|
==========================
|
|
|
|
Some of the features of TC platform referenced in TF-A include:
|
|
|
|
- A `System Control Processor <https://github.com/ARM-software/SCP-firmware>`_
|
|
to abstract power and system management tasks away from application
|
|
processors. The RAM firmware for SCP is included in the TF-A FIP and is
|
|
loaded by AP BL2 from FIP in flash to SRAM for copying by SCP (SCP has access
|
|
to AP SRAM).
|
|
- GICv4
|
|
- Trusted Board Boot
|
|
- SCMI
|
|
- MHUv2
|
|
|
|
Currently, the main difference between TC0 (TARGET_PLATFORM=0), TC1
|
|
(TARGET_PLATFORM=1), TC2 (TARGET_PLATFORM=2) platforms w.r.t to TF-A
|
|
is the CPUs supported as below:
|
|
|
|
- TC0 has support for Cortex A510, Cortex A710 and Cortex X2. (Note TC0 is now deprecated)
|
|
- TC1 has support for Cortex A510, Cortex A715 and Cortex X3. (Note TC1 is now deprecated)
|
|
- TC2 has support for Cortex A520, Cortex A720 and Cortex x4.

Boot Sequence
|
|
-------------
|
|
|
|
The execution begins from SCP_BL1. SCP_BL1 powers up the AP which starts
|
|
executing AP_BL1 and then executes AP_BL2 which loads the SCP_BL2 from
|
|
FIP to SRAM. The SCP has access to AP SRAM. The address and size of SCP_BL2
|
|
is communicated to SCP using SDS. SCP copies SCP_BL2 from SRAM to its own
|
|
RAM and starts executing it. The AP then continues executing the rest of TF-A
|
|
stages including BL31 runtime stage and hands off executing to
|
|
Non-secure world (u-boot).

Build Procedure (TF-A only)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- Obtain `Arm toolchain`_ and set the CROSS_COMPILE environment variable to
|
|
point to the toolchain folder.
|
|
|
|
- Build TF-A:
|
|
|
|
.. code:: shell
|
|
|
|
make PLAT=tc BL33=<path_to_uboot.bin> \
|
|
SCP_BL2=<path_to_scp_ramfw.bin> TARGET_PLATFORM={0,1,2} all fip
|
|
|
|
Enable TBBR by adding the following options to the make command:
|
|
|
|
.. code:: shell
|
|
|
|
MBEDTLS_DIR=<path_to_mbedtls_directory> \
|
|
TRUSTED_BOARD_BOOT=1 \
|
|
GENERATE_COT=1 \
|
|
ARM_ROTPK_LOCATION=devel_rsa \
|
|
ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem
